What Is FAT32 Partition Size Limit and How to Break It

Brithny updated on Feb 20, 2021 Partition Manager | How-to Articles

Overview - What's FAT32 Partition Size Limit

File Allocation Table 32 (FAT32) is one of the oldest Windows file systems. It is a disk file management method that uses 32-bit binary number record management. FAT32 is developed from FAT and FAT16. 

The advantages are good stability and compatibility, fully compatible with Win 9X and previous versions, and easy maintenance. The disadvantage is that the security is poor. FAT32 can only support up to 32GB partition, and a single file can only support up to 4GB.

Name Disk Structure Advantages Limitations
  • Boot area
  • File allocation table
  • The data area
Great stability and compatibility
  • Poor security
  • 4 GB maximum file size
  • 2 TB maximum partition size

4 GB maximum file size: if you try to transfer a file larger than 4GB to a FAT32 drive, you will fail and meet the error "the file is too large for the destination file system". 

2 TB maximum partition size: If you have a 3TB drive, you couldn't format it as a single FAT32 partition

How to Break the FAT32 Size Limit (2 Ways)

You have learned about the FAT32 limitations. How can you break the barrier? To answer this question, you must know another file system, which is called NTFS. 

NTFS is a disk format supported by the Windows NT kernel series operating system, specially designed for network and disk quotas, file encryption, and other management security features. It is superior to FAT32 in many aspects: more secure, robust, and supports larger file sizes and drives.

Thus, you can convert FAT32 to NTFS to break the limit. Generally, there are three ways to convert to NTFS. Only two of them can convert FAT32 to NTFS without data loss.

Method 1. Break FAT32 Limit with Reliable FAT32 Converter

NTFS is ideal for internal drives. To convert to NTFS, you need a reliable FAT32 converter. EaseUS Partition Master is my recommendation. This tool can convert FAT32 to NTFS without losing any data.
